So my D70's shutter locked up tonight at exactly 23000 actuations (you can see the shutter count using exiftool on a NEF file). There is now only a blinking ERR on the top LCD. Looks like I'll be calling Authorized Photo Service in Chicago Monday morning to get an estimate for repairs (it's well out of Nikon warranty). Before I do: 1) Has anyone here had to get their shutter repaired? I'm assuming here the shutter is the problem, and not a symptom of something else (I could very well be wrong). How much does this typically cost? Will I just be throwing good money after bad? Unfortunately I don't have the $2K at the moment to spend on a new D300..$900 on a used D200, maybe. 2) Why exactly 23000 exposures? I'm well aware of the fallacy of attaching any special significance to this, but to crap out at such a nicely even number strikes me as suspicious; as if this was hardcoded by Nikon in the firmware. Any thoughts or comments would be appreciated.
